The SPI of SPIDER - TLE 7240SL provides diagnosis information about the device and about the load. There are
following diagnosis flags implemented:
The diagnosis information of the protective functions of channel n is latched in the diagnosis flag Dn.
The open load diagnosis of channel n is latched in the diagnosis flag OLn.
Both flags are cleared by programming the specific channel to Standby (STB).

Diagnosis Characteristics
Comment
Diagnosis, when channel n is switched on: none
Diagnosis, when channel n is switched off: according to voltage level at the output pin, flag OLn
is set after time
When the channel is in OFF there is Diagnosis active, in Standby the Diagnosis is not enabled
When over temperature occurs, the according diagnosis flag Dn is set. If the affected channel n
was active it is switched off.
The diagnosis flags are latched until they have been cleared by programming the channel STB.
When over load is detected at channel n, the affected channel is switched off after time
and the dedicated diagnosis flag Dn is set.
The diagnosis flags are latched until they have been cleared by programming the channel STB
